I heard of hot tube ignition. Is that the same thing as a hot bulb engine.

On some of the early stationery engines they heated the GP on the exterior of the engine with a torch that burned diesel fuel. The heat would conduct thru the GP from the outside to the inside of the cylinder to aid cold starting same as our electrically heated GP do.
